Abstract: MAGNETIC BRUSH MIXING AUGERS                    Abstract of the Invention Within the sump of a dry developing, magnetic brush system in an office copier machine, twisted strips of aluminum sheet metal are used to form an auger blade mixing arrangement for the purpose of mixing dual component developer.  Each auger blade is formed from strip sheet metal into a single, elongated helical convolution, and is appropriately journaled at each end for the application of rotative power.  In addition, the auger blades have smooth, rounded, axial edges which provides extended useful life to the carrier constituent due to reduced shearing effects.

Abstract: ABSTRACT OF THE DISCLOSURE A wearable infusion system for delivering a fluid medication such as insulin to a patient through a needle, cannula or catheter.  The infusion system includes a medication-filled elongate, thin-walled tubular reservoir and a positive displacement metering assembly operated by a power source under the control of a controller such as a microproces-sor.  The positive displacement metering assembly draws the reservoir inwardly between squeeze surfaces which forces the medication toward the remote end where it discharges through an associated cannula, catheter or needle into a patient.  The rate and frequency at which the metering assembly is operated controls the rate and frequency at which the medi-cation is delivered to the patient.  The tubular reservoir defines a plurality of loops so that a maximum amount of fluid medication may be disposed in a housing.

Abstract: ABSTRACT         Heavy liquid hydrocarbon oils such as petroleum derived tars, predominantly boiling over 425°C, are upgraded to products boiling below 425°C, without substantial formation of insoluble char, by heating the heavy oil with hydrogen and a hydrogen transfer solvent in the absence of hydrogenation catalyst at temperatures of about 320°C to 500°C, and a pressure of 20 to 180 bar for 3 to 30 minutes.  The hydrogen transfer solvents are polycyclic compounds free of carbonyl groups, e.g., pyrene, and have a polarographic reductiong potential which is less negative than phenanthrene and equal to or more negative than azapyrene.

Abstract: OUTERWEAR USED BOTH AS JACKET AND BAG            ABSTRACT OF THE DISCLOSURE:    A new and unique outerwear both as jacket and bag is disclosed which essentially comprises a trunk portion covering an upper half of a human body, said trunk portion being formed with an opening through which a human head passes, sleeve portions through which both arms extend sideways and a head portion detachably secured to the trunk portion, in which the human head is received.  When using the trunk portion as a bag, the sleeve portions are receiv-ed in the trunk portion so that any part of the sleeve portions doesn't protrude outside and the openings through which the arms and head pass are closed.    Specifically, the first opening is formed at the joint between the trunk portion and sleeve portion so that the latter is received in the former through said first opening.          The first opening can be closed by means of a fastener means which is operated after receiving the sleeve portions in the trunk portion.  In the meanwhile, the second opening is formed at the joint between the trunk portion and head portion and can be closed by means of hook means.  When the trunk portion is filled with small-sized goods, it is carri-ed with the both first and second opening closed.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides an improved process for extruding liquid crystal polymer.  The process comprises the steps of providing a fluid stream of liquid crystal polymer wherein the stream has a flow pattern comprising substantial shear flow; converting the flow of the fluid stream of liquid crystal polymer to a substantially elonga-tional flow in the substantial absence of shear flow; and extruding the fluid stream of liquid crystal polymer to form a shaped article having the polymer molecules oriented substantially parallel to the flow direction.  The resulting articles are self-reinforcing, having mechanical properties superior to conventional extruded liquid crystal polymer articles and comparable to those of articles formed from fiber-reinforced isotropic polymeric materials.  In a preferred embodiment, the flow of the fluid stream of liquid crystal polymer is converted to a substantially elongational flow by passing the fluid stream of liquid crystal polymer through at least one grid having a plurality of converging passages (e.g., cone-shaped or trumpet-shaped holes).

Abstract: ABSTRACT There is provided a device for efficient production of light in the low visible range for photo-curing materials, the device being particularly adapted for dental applications.  The efficient light source comprises a tungsten halogen lamp with a concentrating reflector which reflects visible light and passes middle and far infrared wavelengths.  A filter system is pro-vided comprising a dichroic heat reflecting filter which efficiently passes light from 400 to 700 nm and reflects energy in the visible red and near infrared wavelengths back to the lamp envelope, thus enhancing lamp halogen cycle efficiency.  The dichroic heat reflecting filter is followed by a dielectric filter which provides a high efficiency bandpass at the desired visible range. A highly efficient fiber optic light guide is positioned to receive the focused and filtered light and to transmit it to a reduced surface light applying tip at the end of a handpiece.  The fiber light guide is encased in a specially designed sheathing which provides protection to the optical fibers and carries two elec-trical conductors which are connected between a control switch on the handpiece and the power supply for the lamp.

Abstract: Abstract of the Disclosure A propulsion system for an airplane to permit it to achieve vertical and/or short take-offs and landings.  The propulsion system is integrated into a wing/nacelle unit and includes a thrust vectoring system. A separate flow turbofan engine is mounted in each wing/nacelle unit.  A system of three flaps is located at the rear of each wing/nacelle unit for de-flecting the turbofan engine exhaust downward, rearward, or any angle in between.  These three flaps are arranged to provide a main thrust nozzle in the horizontal flight position without any additional flaps between them. One flap is located at the wing/nacelle upper surface trailing edge. Two slots are provided at the leading edge of this flap.  The upper forward most slot is provided as an exit nozzle for the engine tubine exhaust, which is shrouded from the fan exhaust.  The second of these two slots removes a por-tion of the high energy fan exhaust from the fan discharge duct and ejects is over the flap upper surface.  The other two flaps are positioned such that, in the horizontal position they are both aligned with the wing/nacelle lower surface and in the vertical position, one is aligned with the wing/nacelle lower surface and the other is aligned with the wing/nacelle upper surface. When the flaps are in the vertical position, the aft most slot in the upper flap and a slot formed between the upper flap and the lower aft flap provide a means of improving the turning efficiency of the fan exhaust stream.

Abstract: Abstract A shaft arrangement having a transversely displaceable weight member relative to the shaft arrangement's longitudinal axis.  The shaft arrangement includes a housing structure within compression structure is arranged.  The compression structure extends through the housing structure and connects to the displaceable weight member.  An elastomeric member is captured between the compression structure and the housing structure so as to resist transverse displacement of the weight member and the connected compression structure.  The elastomeric member maintains the weight member and connected compression structure in a rotatably balanced position relative to the longitudinal axis for rotation speeds less than a predetermined amount.  When the shaft arrangement is rotated faster than such predetermined speed, the weight member and connected compression structure are transversely displaced so as to induce vibration in the shaft arrangement.
